4 claims.A (o1. eli-sm) This invention pertains to a combined container and applicator for liquids, the applicator being of a special form and construction. I l ,Primarlly, Ythe applicator is designed to be employed in conjunction with a container or reser- 4voirtor. liquids, such for instance aswater` containing an abrasive in suspension and employed for window cleaning purposes, the device or structure having a head which, by' reason of its construction, serves as a ready means for applying the liquid to the surface to be'cleaned and likewise serves asa closure'for the ,container which will normally preclude outpouring and evaporation ofthe liquid.

Moreover, the` construction is such thatV the head may be screwed in place on the container or reservoir upon removal oi the usual screw cap commonly employed to `close a container of the type hereinafter described.

In the drawing:-

Figure l is a side elevation of a can or container with the head of my invention positioned thereon;

Fig. 2, a similar view with the head shown in vertical section, and illustrating the manner in which it is secured to the upper screw end of the container;

Fig. 3, a sectional plan view looking at the upper or outer face of the applicator or head; and

Fig. 4, a bottom plan view thereof.

It will be appreciated, oi course, that the container may be formed of any suitable material, but preferably it will be of sheet metal, or in other words a can, as I, having a top 2 terminating at its upper end in a screw-threaded extension 3. See more particularly Fig. 2.

The can or receptacle, prior to the placement of the head or applicator thereon, is normally closed by the usual screw cap, the cap not being shown as it forms no part of the present invention. Upon removal of the cap, the head or applicator is screwed upon the threaded section 3, as shown in Fig. 2.

In the form illustrated, the head or applicator has embedded in the lower circular portion 4 thereof, a threaded sleeve 5 designed to be screwed onto the threaded extension 3, thus securing the applicator or sprinkler head in place with reference to the can.

t is desirableto have the head present a surface through which the liquid may pass outwardly, materially larger than the can or receptacle opening, and, consequently, the body of the head is given an outwardly iiaring formation.

In the instant case, the body ofthe head is oblong in outline and is formed by oppositely dis- -threaded posed side walls 6 and 'I and end walls 8 and 9, the latter inclining outwardly to a. greater extent as compared to the side walls.

At their upper ends all of the walls merge into an upstanding wall Ill, and extending inwardly i 5 therefrom and at substantially right angles thereto is a continuous ilange-like element denoted by I I. `The flange is oi such extent or measurement as to produce an opening I2, preferably elongated, as seen in Figs. 3 and 4.

The head or those parts thereof so far described, `will preferably be formed of rubber molded to form, with the threaded sleeve 5 securely held within the member or collar 4.

. To secure an even outow and distribution oi the liquid content of the receptacle, there is secured to the-outer face of the flange II, bya suitable cement or otherwise, a block or pad of sponge rubber, or other porous material, such for instance as felt, designated by I3. A portion of the 20 inner face of the block overlies the opening I2 and, hence, as the receptacle is turned from the vertical, the liquid within the receptacle, be it a plain liquid or one containing an abrasive, will pass through said opening and into and through 25 the interstices within the body or block I3.

By reason of the fact that the interstices cornmunicate with each other to a greater or less extent, the liquid will pass to the entire exposed surface of the block or pad. Furthermore, by 30 having the opening I2 elongated to conform to the shape of the block I3, a substantially even distribution of the liquid through and from the block is had.

By the use of the applicator one may readily 35 apply the contents of the container to a windowpane or the like, and if the water contain an abrasive in suspension, allow the same to frost. The window may then be readily wiped off with a dry cloth, leaving the glass clean and brilliant. 40

Several advantages in particular may be adverted to:

First, when once aixed to the container or receptacle the head may be allowed to remain in place, and the necessity of removing it and again applying the screw cap is avoided; and

Second, by forming the walls of the head of a good quality of rubber, the pad may be placed squarely against the surface to be cleaned and the rear end of the container tilted upwardly. The inside of. the head and particularly the'space between flange I I and the cooperating flared walls forms a reservoir in which liquid collects and from which it may overliow through opening I2 and pad I3 when the container is held in sub- 55 stantially a horizontal position or is tilted upwardly. Thus, when the level of the liquid within the container becomes low, the flexibility of the walls, and more particularly the long side Walls, permits the action just described without collapsing or distorting the body to such an eX- tent as to preclude the flow of the liquid from the receptacle through the opening I2 and to the pad I3. When the head is removed from contact with the surface, the structure will assume its normal shape. Consequently, the applicator may Vfuncf tion in a variety of positions and is well adapted to the application of liquid to a vertical surface, such as a window pane, windshield, or the like.

Again, in the case of irregular surfaces which are to be cleaned and to which the pad I3 may not be conveniently applied, the head may be removed and a small quantity of 'the liquid poured upon a cloth, preferably damp, for application to such surface. The head will, of course, thereafter be replaced upon the receptacle to function in its usual manner.

What is claimed is:

.1. A frictional applicator head for liquid kcontainers, comprising a hollow molded rubber structure having a neck constructed and arranged for attachment to the open end of a container; a leX- ible flared body of materially greater cross sectional area than said neck and terminating in an enlarged portion surrounded by a laterally and inwardly extending flage, said flange cooperating with said flared body to form a liquid-retaining reservoir when the container is held in a substantially horizontal position; and a broad flat sponge rubber portion of substantially the same dimensions as the enlarged portion of the flared body, said sponge rubber portion being in contact with and secured to said flange and covering the opening formed by the inner marginal portions of the inwardly projecting flange.

2. An applicator head for liquids, said head comprising a neck portion adapted to be secured to the container for the liquid and an outwardly aring, flexible hollow body portion extending from said neck, said body being formed with an inwardly extending ange at the upper end of the walls of. said body, said flange being of such extent Yas to produce by its inner edge an opening, and cooperating with said flared portion to form a liquid-retaining reservoir when said container is in a substantially horizontal position, all of said parts being produced from rubber molded as an integral structure; and a body of porous material overlying the flange and secured thereto.

3. An applicator head for liquids, comprising a neck portion; an outwardly flaring, laterally elongated, vflexible hollow body portion extending from said neck, said body being formed with an inwardly extending ange at the upper end of the walls of said body portion, said flange being of substantially the same width throughout and cooperating with said neck to form a liquid-retaining reservoir, whereby an elongated opening is formed between the inner marginal portions of `said iiange and liquid may be held in said reservoir, all of said parts being produced from rubber molded as an integral structure; and a continuous body of porous material overlying the nange and opening, and permanently secured to the flange, the outer surface of said body forming the working face of. the applicator1 4. A structure as set forth in claim 3, wherein the body which 'overlies the ilange and is secured thereto, is formed of sponge rubber.
